Ms Walley

To ask the Secretary of State for Trade and Industry (1) what recent representations her Department has received regarding the technology and engineering involved in hydrological fracturing; [7346]

(2) what recent research has been done by her Department into the effects of hydrological fracturing; [7347]

(3) what (a) quantitive and (b) qualitative research methods were used in studies by her Department on hydrological fracturing; who commissioned such studies; and what examples of field trial stages have been published; [7345]

(4) what recent research has been completed by the relevant authorities on the environmental, commercial and social effects of hydrological fracturing. [7349]

Mr. Wilson

My Department, as part of its Cleaner Coal Technology Programme, has funded a number of projects that included work on hydrological fracturing, although it has not commissioned specific R&D on this subject.

The Natural Environment Research Council (NERC) has funded research into hydrogeology, including the hydrological fracturing of rock and other media. NERC's British Geological Survey (BGS) has undertaken work reviewing the use of the technology of fracturing in Coal Bed Methane production. A list of the NERC research portfolio, including grants funded through NERC's Micro to Macro programme, is listed below on Annexe 1.
